My back seat is often very damp. I cant seem to find where the leak is. Anyone else have this issue?

Thanks.

 

Have you removed your taillights before? If so, that's what causing the leak. I removed mine before and didn't put them properly, after that I've been getting water under my backseats. The water builds up where your spare tire is and splashes forward when the car moves. It's fixed now though.

 

Yes I did replace them. Did you switch back to the OEM lights?

 

If you replaced them, take the seal off of the OEM tails and put it in the aftermarket tails. It will solve your problem, hopefully.
